Abstract
A screwdriver includes a grip defining an accommodation chamber, an inner tube with interference holes mounted in the accommodation chamber, a rod member movable in and out of the inner tube and having interference grooves corresponding to the interference holes and a neck and carrying a latching member, an operating device set, which includes an operating member rotatably mounted at the front side of the grip, interference members and an actuation member having a pressure wall for holding down the interference members, a first elastic member, a ring cap having an axial hole and a stop wall around the axial hole for stopping the latching member, and a second elastic member. Thus, the screwdriver is operable by rotating the operating member and effectively prevents the rod member from being ejected out of the grip.
